    Tanzanite – a rarity in the realm of gemstones

    Tanzanite – a blue variety of the mineral zoisite – is one of the best-selling colored gemstones of all time. This is likely due to its unique blue hues – depending on the viewing angle and the incidence of light, the color appears blue, purple, or brown-yellow. Its color spectrum thus ranges from deep sapphire blue and blue-violet to soft lavender and purple. This highly sought-after gemstone is a thousand times rarer than a diamond and is therefore an extremely valuable gem. Tanzanite cannot yet boast a particularly long history – after all, it was only discovered in 1967. But where does tanzanite come from? There is only one region in the world, a few square kilometers in size, that produces it in the highest gemstone quality: near the border between Kenya and Tanzania at the foot of Mount Kilimanjaro, not far from the city of Arusha. This also answers the question of the origin of this gemstone – a creative twist on its country of origin, Tanzania. Although a Pakistani deposit is now known, the gemstones found there are nowhere near as high quality as those from Tanzania.

    The Tanzanite and its exciting play of colors

    The most beautiful tanzanites shine in a sapphire blue, which tends towards the violet of amethyst under artificial light. A special phenomenon of tanzanites is their so-called pleochroism or trichroism, which means that each tanzanite crystal exhibits three colors: blue, a purple-red, and a greenish-yellow brown (bronze). The intensity of each color depends on the viewing angle. The larger the tanzanite, the more intense its color. The most sought-after color is a blue with a slight hint of purple. Smaller gemstones often still have brownish undertones – which is why most rough tanzanites are heat-treated to eliminate the brown-yellow areas that often appear in the crystals. At 550 degrees Celsius, this color changes to blue – a commercially available process that requires inclusion-free rough stones. This is precisely why tanzanites are so well suited to this treatment: they are generally eye-clean, meaning there are no visible inclusions when viewed with the naked eye. The high degree of transparency and the absence of inclusions emphasize the magnificent colors of the tanzanite and are therefore trademarks of this colored gemstone. A slight color change effect can also be observed: in daylight, a high-quality tanzanite is ultramarine to sapphire blue, but in artificial light it is more amethyst-colored. The already mentioned, extraordinarily high transparency contributes significantly to the great popularity of tanzanite and is particularly impressive in a faceted cut. In principle, this gemstone is available in a wide range of different cuts – although oval and cushion cuts are the most common in the world of tanzanite. But does this achieve the best possible effect? ​​The beauty of your tanzanite is best displayed as a faceted piece of jewelry or as a cut cabochon .
